Runner for motor-sleighs.

Application To all whom it mag concern:

e'it known thatI', ROY S. HAIGHT, asubject oft'he King of England,residing'at Viking, in the Province of Alberta, Dominion of Canada, haveinvented certain new and'useful Im rovements in Runners forMotor-Sleighs, of which the following is a specification; j v Thepresent invention relates in general to sled propelling larly to animproved runner for noto'r j sleighs which embodies I novel features ofconstruction whereby the -sled can be pro-- pelled in a positive andreliable manner, and whereby the t r a'ctive .powerof the runner can'beincreased or decreased as may be re 'quired bythe conditions otthe roadsurface. One of the Objects ot'the inv'ention is to provide a motor sledwhich is comparatively simple and inexpensive .inits construction, whichcomprises few and durable parts such-'as'are notliab'le to get out ofrepair, and which-will operate with the expenditure of a minimum amountof power.

'Vl' ith these and other objects in View the invention-consists incertain novel bombinations and arrangements-or" the parts as willmore'tully appear as the ,dpscription proceeds, t e'novel featuresthereof'being'pointed out 1n the appended claims.

For a full understanding oftthe invention reference is to be had to thefollowing description and accompanying drawings in which:

Figure 1 is aside elevation of a motor sled constructedin accordancewith the invention, portions being broken away to more clearlyillustrate the construction of the runner, and Fig. transverse sectionalview 2 is a through the sled, portions being broken I away.

Corresponding andlike parts are referred to in the fOllOWID desert tionand indicated l: i t

1n all the vlews of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the sled platformwhich is sup} l ported by means of a series of runners 2, one

the present instance as located at each side of the platform, althoughthe exact arrangement of these runners is quite immaterial'so far as theessential-features of the invention are concerned. Each of the runners 2is formed with a pair of\ spaced side pieces 2 which 1 are rigidlyconnected, guide or sprocket RUNNER FOR MOTOR-SLEIGHS.

The invention further contemplates the provision of means whereby thelower reach of the endless chain a between the guide wheels 3 can bemoved up and down to regulate thedistance the traction teeth 5 project'below the runner, tractive power of the runner to be readily adjustedfor either a hard icy surface or-a soft and slushy road. A guide bloc-l:11 is movably mounted between the sides 2? of the runner at a point overthe lower reach of the endless belt 4 the said block being shown ashaving an elongated formation and provided with curved ends. This blocl:may be very readily formed, as indica upon the drawing, by suitablybending a ot' T-iron so as to provide an endless'ri A chain of rollers12 ex the exterior of the guide hlocl: interposed between the said guidebloci the endless chain 4- so as to reduce'the tion and prevent anypossible bindi said chain at in the operation of the der'ce. chain ofrollers moves with the drive or traction chain l, and"the block 11 canbe moved up and down within therunner so as to cause thetraction teeth 5to project a greater or less distance below the runner may be required.
